What analog designer hasn't had to derive a nonstandard resistor value by using series/parallel combinations of standard resistor values? In efforts to avoid a production trimpot tweak, we can use 0.1 ...

In this circuit, the dc bias for the noninverting circuit is derived from the inverting amplifier's source resistor (bias is required because the input is ac-coupled).

Real circuits will have combinations and thus will have a combination of real and imaginary parts. Numbers like that are complex numbers and you can write them in several different ways. Complex ...

All parts announced so far have a single normally-open contact, and there is a choice of two resistor arrangement dubbed ‘parallel’ (right-hand in diagram right) right, or ‘series’ (left-hand) – the ...
